Enjoyed on cask at the brewery. No head on a hazy amber body. Aroma is very strong, almost like opening a bottle of Evan Williams ( barrel used to aged this one) and taking a whiff. Dark chocolate, toffee and caramel notes as well. Very heavy on the bourbon which, after having the base beer straight up, completely obscured the base wee heavy brew. Some brown sugar and caramel malt, otherwise mosty bourbon. Medium body and casked. The one doesn't blend the base beer well with the barrel.
